Announced last Thursday, by existing monument around U.S. controlled islands, it will be the largest marine reserve ever.  Acting quickly, for the 12th time Obama has bypassed Congress and used the Antiquities Act for environmental protection. It will expand the reserve while some parts are untouched. Three times the size of California, 6 times it's original, at 490,000 square miles. Even with the enormous amount of expansion, it is nowhere near the size of 754,400 square miles that President Obama was hoping for. This will take effect in January of 2015.

How fast can humans run?

After 40 years in the dark, this question was finally answered. Experiments to see how fast a human can run on the moon has taken place. Taking place on NASA's DC-9 aircraft. An aircraft capable of reducing its internal gravity to the match the moon's while in the swooping motion. There were eight participants, three being astronauts. Each astronaut was asked to run for 20 seconds long in the artificial lunar gravity.

The theoretical average calculated by NASA was 1.8 miles per hour (2.89 km), was a dramatic difference to the average on Earth being 4.5 miles per hour (7.24 km). After the experiments, the results was an average of 3 miles per hour (5 km), a much closer calculation. The theory revolving around why their theoretical calculation is the boost created by the counter-swinging motion of the participants' arms and legs.

How 3D printing can change our lives.

The first 3D printed object was created in 1984 by Charles W. Hull. From the cost of $20,000 for a printer to only $1,000 in the course from 2010 to 2013 alone. Now this technology no less than 2 years has been growing in popularity and the uses of it. As in my last blog, NASA has made a rocket injector (fuel injector) using 3D printing. As more attention is attracted to this technology, more of the bigger companies are buying printers and coming up with cheaper and easier ways to innovate. As it began growing in popularity, their uses were only for creating small objects such as cups or decorations. Since then, now their uses range far and wide, ranging from a mere simple printed name to a working bicycle to a working weapon. Caused by the uses and possibilities this provides, are many risks and many dangers. The reliability and efficiency it provides even NASA has uses for it. Instead of sending a space ship to give simple tools to the space station, a new one can be printed on the station. As NASA plans to send 3D printers in space for use, a Boston hospital recently 3D printed a toddler's brain before his actual hemispherectomy to insure success. Hemispherectomy is one of the rarest and most challenging surgery which half of the brain is removed or disabled. The versatility is said to boost economies and help smaller businesses.
